Usama bin Zayd reported,

Usama bin Zayd reported that he heard him say, "The Messenger of Allah ﷺ departed from Arafah, and when he reached the mountain pass, he dismounted, relieved himself, then performed a light ablution without doing it thoroughly."I said, "The prayer, Messenger of Allah?"He replied, "The prayer is ahead of you."So he mounted again, and when he arrived at Muzdalifa, he dismounted, performed ablution thoroughly, then the call to begin the prayer was given and he prayed Maghrib. After that, each person settled his camel at his place, then the call for Isha was given and he prayed it, without performing any prayer between the two.

حدثنا عبد الله بن مسلمة عن مالك عن موسى بن عقبة عن كريب مولى ابن عباس

عن أسامة بن زيد

أنه سمعه يقول دفع رسول الله ﷺ من عرفة حتى إذا كان بالشعب نزل فبال ثم توضأ ولم يسبغ الوضوء فقلت الصلاة يا رسول الله فقال الصلاة أمامك فركب فلما جاء المزدلفة نزل فتوضأ فأسبغ الوضوء ثم أقيمت الصلاة فصلى المغرب ثم أناخ كل إنسان بعيره في منزله ثم أقيمت العشاء فصلى ولم يصل بينهما
